My check engine light is on. There is a " knocking"sound coming from the engine. The engine shakes a little. I thought it was the spark plugs, but i disconected one at a time and started the truck. It didnt go away. I think it might be a stuck valve. How can you check for a stuck valve? Someone from work told me that it could dirty fuel injectors, i tried to clean them out, but the problem still occurs. I think its time to take it to the dealer and pay WHATEVER it takes to fix it.. does anyone know what my problem could be. Any input is greatly appriciated.
